B OX-SE ALING DE VICE Specification of Letters Patent.

Patented Dec. 15, 1608.

To all whom it may concern:

Be it known that I, EDGAR M. OLERKE, a citizen of the United States of America, and a resident of Hillsdale, in the State of New Jersey, have invented a new and useful Improvement in Box-Sealing Devices, of which the following is a specification.

This invention relates primarily to means for securing wooden boxes or packin cases with the aid of metallic box-straps fly the seals set forth in United States Letters Patent No. 822577 dated June 5, 1906, Nos. 837788 and 837789, dated December 4,

1906, and No. 847276, dated March l2,

1907, articularly the latter, granted to Edward Brooks; but the box sealing devices to which the present invention is confined are applicable as means for ti htening boxstraps in general, including wire as well as thin hoop-iron.

This invention consists in certain novel combinations of parts hereinafter set forth and claimed, and in a box sealing device embodying the same or any of them.

The leading objects of the invention are to provide for stretching the box stra around the box with sufficient force to em ed it in the wood at the corners of the box, and thus to render the nail driven through the seal all that is required to inseparably attach the box strap; and to provide, at the same time, for exposing the ends of the box strap preparator to ap lying the seal.

ther o jects will be set forth in the general description, which follows.

Three sheets of drawings accompany this specification as parts thereof.

Figure 1 represents a top view of a box sealing device, in operation, embodying all the features of the present invention; Figs. 2 and 3 are top views of the same with the winch art removed, further illustrating the operation of the device as hereinafter described; Fig. 4 is a view of the winch detached, with the slotted end of its shaft in the fore round; Fig. 5 is a view of one of the catches ereinafter mentioned, showing it in its two positions by full and dotted lines;

Figs. 6 and 7 represent vertical sections on a larger scale on the lines AB and CD,

Fig. 1, respectively, illustrating by the positions of the parts and by dotted lines in Fig. 7, the beginning and completion of the strap tightening operation; Figs. 8 and 9 represent cross sections on the lines E-F and GH, Fig. 6, respectively; Fi 10 is a top view of the second s ecies of t e device on the same scale as igs. 1-5; Fi 11 is a front view of a third species of t e device; Fig. 12 is a top view of the latter; Fig. 13 is another front view of the same, with its winch removed; and Figs. 14 and 15 represent cross sections on a larger scale on the lines IJ and KL, respectively.

Like reference characters refer to like parts in all the figures.

Each of the improved box sealing devices is characterized by a rotatable and removable winch part a, which ma be of one and the same construction in al the species; a frame part, b or b, which may be and preferably is of one and the same construction (1;) in the first and second species; and a dog, 0, which may be of one and the same form in all the species; the latter interacting I with a ratchet wheel, 0, forming part of said winch a. Provision is also made in each of ends of the box stra d, preliminary to the removal of the wine a and the application of the seal, 6, Figs. 3 and 15, by drivlng a nail, f, Fig. 15, therethrough, which nail is the permanent and only fastening of the box-strap d after it is freed from the temporary fasten- 1 ings of the respective species, which are represented at gh, gh and gh, respectively. To render this practicable the winch a is adapted to so tighten the box strap d by tension on both of its ends, as to embed the box strap in the corners at least of the wooden box, as represented at t in Figs. 7 and 13, so that after its resiliency takes up the small amount of slack that may remain when the box strap is freed from the temporary fastenings g h, h or g72,, the box strap will be securely held in place on the box, 1' or 7', at all points. Said winch a, in each of the s ecies, is composed of a hand crank and a s otted shaft, shown respectively at l and 2 in Fig. 4 especially, together with the aforesaid ratchet wheel 0. These parts are integrally or fixedly united with each other; and

the species for temporarily fastening both i the slot, 2, Fig. 4, of the slotted shaft, is an open slot extending through its free end. During the tightening operation, the winch a turns in suitable bearings, 3 or 3, in the frame part, I) or b; and its ratchet wheel 0 interacts with the contiguously supported dog 0. The extremities of both ends of the box strap d are inserted endwise through the slot 2 in the shaft of the winch a preliminary to the tightening operation, and'at the conclusion of this operation are in the form of a coil as shown at d in Figs. 7 and13.

When the box strap d is considered sufliciently taut, its respective ends are temporarily secured by said fastenings gh, g7a/ or gh; the dog 0 is disengagedfrom the ratchet'wheel c by turning it on'its pivot, 4, and the winch a is then withdrawn or separated from the frame part b or b. In the first and second species, this is done by lifting the winch a bodily, and allowing it to turn so as to unwind the coiled ends of the box strap. In the third species the winch a is withdrawn endwise; the open-ended slot 2 of the winch shaft permitting it to free itself from the coiled ends of the box strap d, which are afterward unwound by the fingers.

In the first species, represented by Figs. 1 to 9 inclusive, the frame part I) is a sub stantially rectangular block, which may be either of suitable wood or metal, having a substantially central recess, 5, extending therethroughfrom top to bottom, and shal low guide notches, 6 and 7, Fig. 7, in its bottom at its respective ends, through which the respective ends of the box stra (Z are draw-n and the bearings 3 of the sha t of the winch a are central notches in the top of the frame part b. The dog a is attached'to the top of the'frame 1 part b by its pivot 4; and

both ends of the ame part are provided at or immediately above said guide notches6 and 7 with-pairs of lugs, 8 and 9, between which a pair of strap engaging arms, is and Z, are hinged to the frame part b by horizontal pintles or trunnions the hinged end of each of the arms 7c and Z being further provided with a hinge joint, 10, having a vertical axis. The arms 7c and Z are of'the constructionbest shown in Figs. 6 to 9 inclusive, which see. Each arm is constructed with a pair of depending lips, 11 and 12, Fig. 9, to engage the edges of the box strap 61, and with a sliding clip, 13, which in its effective position, represented in Figs. 1, 2, 6 and 7 and in full lines in Fig. 8, serves to keep the box strap a between said depending lips 11 and 12, and thus insures their effectiveness. Each arm is further constructed with a slotted outer end-portion, 14, connected with the body of the guide by a shoulder, 15, so as to maintain an elevated position with reference to the box strap, as in Figs. 6 and 7, andis provided with one of saidtemporary fastenings gh in the form of a sharp pointed punch or nail held in place against accidental sep aration by a headed up er'end and asubjacenteollar, 16, with su cient space between to permit the nail g or 7i to be driven endwise through the box stra d, to temporarily fasten the latter, as in otted lines in Fig. 7.

The fastenings gh are moved to the inner ends of the slots in said slotted portions 14 of the arms 70 and Z before driving them, and are then driven like ordinary nails through the box-strap d, and into the box, which is represented at in Figs. 6 and 7 The winch a is then disengaged from the ends ofthe box strap (1 and'separated from'the frame part b as above described, and the frame part is then moved clear ofthe box-strap as in Fig. 3. In this movement the longitudinal slots in said slotted end portions 14 of thearmsg and h permit the arms to move endwise with reference to the temporary fastenings gh to the necessary extent. The seal 6, Fig. 3, is next applied to the ends of the box strap (Z, and'pressedinto the seal inclosing recess 17 in the box 3, and the strap ends are per manently secured by driving-the seal nail The nail-pulling claw of an ordinary hammer or the like is then introduced beneath the outer end ofeach-of'the arms is and l so as to withdraw the temporary fastenings gh, and the arms may then be turned up ward against the frame part as represented at 7c in Fig. 6, and temporarily secured in this position by catches, 18 and 19, onthe ends of the frame I), so that the whole can be conveniently handled. One of'these catches is shown detached by Fig. 5, andthe pivot by which it is attached to the frame I) is represe'ntedat 20.

In the second species, represented by Fig. 10,- the winch a, frame part b and dog 0 are identical with those of the first species, above described, and require no further description. In this species, instead of providing the ends of the frame part with arms having temporary fastenings gh permanently attached thereto, a pair ofsharp-pointed nails gh are driven through the box strap (1 into the box 9' at the end of the strap-tightening operation; and the frame part b with its appurtenances, as well as the winch part a, is immediately removed to expose the ends of the box strap for the sealing operation.

In the third species, represented by Figs. 1 1 to 15 inclusive, the frame part b is in the form of a clamp bar, preferably and conveniently rectangular in cross section, provided with a pair of knees, 21, 22, one of which forms the internal screw or nut for a clamping-screw, 23, while the other is movable on the framepart bar I) and attachable thereto in diifer ent positions by a removable pin, 24, interacting with any one of a series of vertical frame piece quickly to the box 7' which is to be sealed. The winch bearings 3 are in the form of a series of holes extendin horizontally through the frame-part bar so that the winch a may be located advantageously with reference to the desired location of the seal-inclosing recess 17 and seal 6. The dog 0 is attached by its pivot 4 to a support, 26, movable with reference to the frame-part bar 6' so as to be clamped thereto in proper position with reference to the winch bearing 3 that is for the time being in use. Its clamp bolt, 27, extends horizontally through the appropriate hole 28 of a series in the framepart bar I), which is further provided with slots, 29, for the accommodation of clamping screws, 30, by which the temporary fastenings g-h are held in effective position with reference to the winch a in the various positions of the latter, so as to temporarily fasten the box strap (1 on the respective sides of the winch a as in the first two species. These temporary fastenings gh are in the form of lever operated clamps of known construction, the housings of which are attached to said clamping screws 30 by which the temporary fastenings 'are attached to the frame art I) In this arrangement, the frame part may remain in position, and the temporary fastenings gh attached thereto may continue to perform their functions until the sealing operation is completed, after which the frame part, b, with its accessories, including said temporary fastenings gh, may be unclamped and removed from the box. The temporary fastenings (gh, gh or g-h) ma obviously be of other known or improved orms; and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specification:
